Definitions

  • the invention relates to an apparatus for measuring and delivering predetermined quantities of liquid, for example quantities of water, comprising a measuring vessel, to which a liquid supply pipe and a liquid discharge pipe are connected.
  • An apparatus of this kind which for example serves for delivering a predetermined quantity of water with a required temperature as a water charge for a dough tub in a bakery.
  • This known apparatus comprises a measuring vessel, to which the quantity of water necessary for a charge, is supplied through supply pipes for hot and cold water, which supply pipes alternately deliver hot water and cold water in the measuring vessel and are connected to a water pipe, which debouches in the vicinity of the bottom of the measuring vessel.
  • Valves are accommodated in the water supply pipes, which valves may be operated by means of a thermostat, which communicates with a temperature feeler means in the measuring vessel, which on the one hand feels the temperature of the surrounding water in the measuring vessel and on the other hand feels the temperature of the water supplied to the measuring vessel and which controls the changing over of the thermostat before the temperature of the surrounding water in the measuring vessel has reached the required temperature.
  • This known apparatus has operated satisfactorily in practice, but is rather voluminous as the contents of the measuring vessel has to be equally large as the maximum quantity of liquid necessary for a charge, which may for example amount to 1000 litres.
  • the apparatus according to the invention is characterized in that a lower and an upper stationary measuring means are mounted in the measuring vessel, which measuring means serve for measuring a fixed quantity of liquid in the measuring vessel and for controlling the liquid supply to and the liquid discharge from the measuring vessel, while the measuring vessel further comprises a displaceable measuring means, which causes the liquid supply pipe to close and the liquid discharge pipe to open when a set residual quantity of liquid is supplied in the measuring vessel.
  • a small measuring vessel of for example 25 litres, which, dependent on the quantity of liquid required for a charge, can be filled a number of times with the fixed quantity of liquid and subsequently can be emptied, whereafter the displaceable measuring means controls that the required residual quantity of liquid is supplied to the measuring vessel and is thereafter delivered by the measuring vessel.
  • this apparatus comprises at least one more measuring vessel, which is also provided with a lower and an upper stationary measuring means, which serve for measuring a fixed quantity of liquid in this further measuring vessel.
  • a predetermined quantity of liquid can be delivered very quickly, in particular when the liquid supply to and the liquid discharge from these measuring vessels are controlled in such a way, that always one measuring vessel is filled, while another measuring vessel is emptied.
  • the apparatus may comprise a further vessel, which is located at a lower level than the first mentioned measuring vessel and which is connected with the first mentioned measuring vessel by means of a connecting pipe, in which a valve is accommodated, which valve opens when the liquid level in the first mentioned measuring vessel reaches the height which is determined by the upper stationary measuring means or by the displaceable measuring means respectively, while this valve closes when the liquid level in the first mentioned measuring vessel has fallen until the lower stationary measuring means is reached, the further vessel being provided with a liquid discharge in which a throttle valve is accommodated.
  • this alternative embodiment is that less valves are necessary, so that this apparatus can be manufactured at less costs.
  • this alternative embodiment of the apparatus according to the invention has the disadvantage, that the discharge speed of the liquid from the further vessel is slower than the discharge speed of the preceding embodiment of the apparatus according to the invention.
  • This apparatus comprises a first measuring vessel 1, to which a liquid supply pipe 2 and a liquid discharge pipe 3 are connected.
  • a lower and an upper stationary measuring means 4 and 5 respectively are accommodated in the measuring vessel 1, which measuring means serve for measuring a fixed quantity of liquid in the measuring vessel 1 and which may each consist of a level switch.
  • the measuring vessel 1 further comprises a displaceable measuring means, which in both embodiments comprises a float 6 and which serves for measuring an adjustable residual quantity of liquid in the measuring vessel 1.
  • the apparatus according to fig. 1 further comprises a second measuring vessel 7, which is also provided with a lower and an upper measuring means 8 and 9 respectively, which serve for measuring a fixed quantity of liquid in this measuring vessel 7 and which may again consist of level switches.
  • the measuring vessels 1 and 7 are arranged for delivering an equal fixed quantity of liquid.
  • the displaceable measuring means applied in both embodiments is shown more in detail in fig. 3.
  • the float 6 is suspended from the cable 10.
  • the end of this cable, which is remote from the float 6 may be wound on a winding reel 11, which is subjected to a constant winding moment, while a detector 12 reads the position of the float 6.
  • the constant winding moment is exerted on the winding reel 11 by a spring 13, which comprises parts 14, 15 wound in opposite directions and which engages a shaft 16, on which the winding reel 11 is mounted.
  • the cable 10 drives a counting roller 17, which has a plurality of holes, which counting roller is scanned by the detector 12, which e.g. consists of a photoelectric cell.
  • the measuring means 4, 5, 8, 9 and 12 emit signals to a microprocessor 18, which indicates on a digital indicator 19 the number of litres required for a certain liquid charge, e.g. 85 litres.
  • the microprocessor 18 divides this volume by the contents of the measuring vessels 1, 7 determined by the stationary measuring means 4, 5 and 8, 9, which contents e.g. amounts to 25 litres and further computes the residual quantity, in the present case 10 litres.
  • the microprocessor .18 determines which measuring vessel, 1 or 7, is first filled and emptied, in the present case the measuring vessel 7, whereafter the microprocessor 18 controls magnet valves 20 in the liquid supply pipes 2 and in the liquid discharge pipes 3 in such a way, that first the measuring vessel 7 with the fixed liquid quantity of 25 litres is filled, whereby the liquid level in the measuring vessel 7 reaches the upper stationary measuring means 9, while thereafter this liquid quantity is delivered again, whereby the liquid level in the measuring vessel 7 falls until the lower measuring means 8 is reached, whilst simultaneously with the discharge of liquid from the measuring vessel 7 the measuring vessel 1 is filled with the fixed liquid quantity of 25 litres.
  • the measuring vessel 7 is filled for the second time with the fixed liquid quantity of 25 litres, whereby during the discharge of this liquid quantity from the measuring vessel 7 the residual quantity of 10 litres is supplied to the measuring vessel 1, whereby the detector 12 emits a signal to the microprocessor 18 when this residual quantity is supplied into the measuring vessel 1.
  • the residual quantity of 10 litres is discharged from the first measuring vessel 1, whereafter the quantity of liquid of 85 litres required for a charge, is obtained.
  • the liquid discharge from both measuring vessels 1, 7 can take place uninterruptedly and uniformly by the accommodation of throttle valves in the liquid discharge pipes 3, which take care that the filling time and the emptying time of the measuring vessels -1, 7 are exactly the
  • the program of the microprocessor 18 may be provided withthepossibility of introducing a multiplying factor, with which deviating dimensions of the measuring vessels can be compensated for, or with which litres of liquid with a certain specific weight may be conversed into kilogrammes. Also a compensation factor for the different liquid weights at various temperatures can be introduced.
  • Fig. 2 shows a modified embodiment of the apparatus for measuring and delivering predetermined quantities of liquid, e.g. quantities of water.
  • This apparatus is again provided with a measuring vessel 1 having a liquid supply pipe 2, in which a magnet valve 20 is accommodated, and a liquid discharge pipe 3, which also comprises a magnet valve 20.
  • the measuring vessel 1 also comprises a displaceable measuring means, which is constructed in the manner as shown in fig. 3 and which comprises a float 6.
  • the apparatus according to fig. 2 is further provided with a vessel 21, which is located at a lower level than the measuring vessel 1 and which is as large as the measuring vessel 1.
  • the measuring vessel 21 is connected with the measuring vessel 1 by means of a liquid discharge pipe 22, through which the liquid of the measuring vessel 1 can flow to the vessel 21.
  • the magnet valve 20 in this liquid discharge pipe 22 is controlled from the microprocessor 18 in such a way, that this magnet valve 20 opens when the liquid level in the measuring vessel 1 is reached, which is determined by the upper stationary measuring means 5 or by the detector 12 and the float 6, while this magnet valve 20 closes when the liquid level in the measuring vessel 1 has fallen until the lower _stationary measuring means 4 is reached.
  • the vessel 21 is provided with a liquid discharge 23 in which a throttle valve 24 is accommodated, which is set in such manner that the sum of the supply time and the discharge time of a liquid volume unit - such as 1 litre - to and from the measuring vessel 1 is at least approximately equal to the time which is necessary for discharging this liquid volume unit from the measuring vessel 21.
  • the vessel 21 can never be empty before the measuring vessel 1 delivers liquid to the vessel 21 by opening the magnet valve 20 in the liquid discharge pipe 22, which magnet valve is controlled by the microprocessor 18.
  • the embodiment according to fig. 2 requires considerably less nagnet valves 20 than the embodiment according to fig. 1, so that the embodiment according to fig. 2 can be manufactured at less costs.
  • the embodiment according to fig. 2 has the disadvantage that the velocity of the discharge of the liquid from the vessel 21 has to be smaller than the velocity of the liquid supply to the measuring vessel l,that is to say the velocity of the water supply from the water main in the case that the liquid is water.
